[00:18:56]<djdelorie> yes, I wrote the GNU assembler and simulator for it
[00:19:19]<djdelorie> and I've done lots of hardware projects with them, including my BLDC controller, which uses an RX62T processor
[00:21:09]<djdelorie> why?
[00:22:09]<Thetawaves> i'm curious about endianness
[00:22:32]<djdelorie> it has both. Use little endian :-)
[00:22:43]<Thetawaves> i *have* to use little endian
[00:22:47]<djdelorie> unless you're doing CAN, that peripheral is endian-weird
[00:23:20]<Thetawaves> i noticed that instructions only seem to be stored in big endian, while data can be stored as little endian
[00:23:29]<djdelorie> (you can still do little endian with CAN, but you have to use different code to read/write some of the registers)
[00:23:33]<Thetawaves> all of my little endian dependent logic will still work?
[00:23:51]<djdelorie> instructions are stored as a byte stream
[00:24:03]<djdelorie> my projects are always little endian
[00:24:25]<Thetawaves> cool
[00:24:37]<Thetawaves> is it a relatively fun processor to work on?
[00:24:46]<djdelorie> yes :-)
[00:24:59]-!- micges has quit [Quit: Leaving][00:25:04]<Thetawaves> ok great
[00:25:13]<djdelorie> lots of peripherals, single-cycle FPU, wide range of chip sizes, etc.
[00:25:19]<djdelorie> linux tools :-)
[00:25:29]<Thetawaves> linux tools is a huge advantage
[00:25:39]<djdelorie> (some of which you get from me, like the flash downloader)
[00:25:44]<Jymmm> What happens to feed point impedance at the base of a fixed-length HF mobile antenna as the frequency of operation is lowered?
[00:25:49]<djdelorie> all my RX development is linux-only.
[00:25:52]<Jymmm> sorry
[00:25:59]<Thetawaves> i didn't select the pic32 because the compiler isn't integrated into gcc mainline
[00:26:18]<djdelorie> RX is, I use gcc "head" as my regular compiler
[00:26:19]<Thetawaves> what kind of programmer do you use? do you have jtag?
[00:26:36]<djdelorie> I use the serial bootloader. The JTAG interface isn't (and likely won't) be documented.
[00:26:57]<djdelorie> the serial bootloader is documented in the many-thousands-of-pages-long hardware documentation.
[00:27:04]<Thetawaves> don't use jtag anyway, so not a deal breaker
[00:27:33]<djdelorie> I have a schematic for a standard FT232R-based interface, too, which gives you the linux tool support and a printf console
[00:27:34]<Thetawaves> serial bootloader... i'll take a look
[00:27:48]<Thetawaves> bootloader comes with the chips?
[00:28:29]<djdelorie>http://people.redhat.com/~dj/m32c/ - the r8c/etc programmer includes RX too. The bootloader is pre-flashed in a separate flash area in the chip, it's always there.
[00:29:07]<djdelorie>http://www.delorie.com/electronics/rx/ & http://www.delorie.com/electronics/rx-stick/ have most of the stuff I've done hardware-wise.
[00:29:26]<Thetawaves> how do you configure it to boot directly to your code?
[00:29:52]<djdelorie> there are two mode pins on the chip; their values at reset determine the chip's mode
[00:30:06]<djdelorie> it chooses between serial bootloader, USB bootloader, and your program.
[00:30:17]<Thetawaves> very cool
[00:30:49]<djdelorie> if you haven't gotten hardware yet, consider http://www.delorie.com/electronics/rx/rx62n-breakout.html - I still have plenty and they're linux-friendly.
[00:31:15]<djdelorie> (plenty of blanks, that is, I build the full ones as needed)
[00:31:50]<djdelorie> here's the RX62T bldc controller board: http://www.delorie.com/electronics/bldc/[00:31:50]<Thetawaves> how much for the parts kit?
[00:32:13]<djdelorie> dunno at the moment, my digikey BOM script is broken.
[00:32:42]<djdelorie> the chip is around $16, plus $5 for the usb chip, add a few dollars for connector and discretes as needed, etc
[00:33:41]<Thetawaves> i certainly would like to get a reference board
[00:34:01]<djdelorie> Renesas has a bunch, but they're not all linux-friendly.
[00:35:42]<djdelorie>http://www.digikey.com/product-detail/en/YRDKRX62N is a good one
[00:36:13]<djdelorie> but it needs a resistor swap to do USB bootloader
[00:38:28]<Thetawaves> i'd rather get your breakout board
[00:38:40]<Thetawaves> i just don't want to spend the time trolling digikey to get the parts
[00:39:14]<djdelorie> there's a BOM for digikey right on that web page
[00:39:42]<djdelorie> unless they obsoleted some of the parts on me :-P
[00:40:52]<djdelorie> heh... the bom includes everything *except* the MCU
[00:41:39]<Thetawaves> why do you have two boms with different size smd?
[00:41:43]<djdelorie> also, I've been having bad luck with the RTC clock circuit on my boards, don't know why.
[00:41:52]<Thetawaves> :O
[00:42:08]<djdelorie> The PCB allows for either size part, so you choose whatever size you mostly have in stock. My stock is mostly 0603, for example.
[00:42:24]<djdelorie> I suspect it's my choice of crystals
[00:43:08]<djdelorie> the renesas board uses an SMT crystal, but that's hard to hand-solder so I had to go with a canned crystal instead.
[00:43:23]<Thetawaves> i downloaded your schematic for the breakout board, and man is that a weird clock circuit
[00:43:44]<djdelorie> which clock?
[00:43:58]<Thetawaves> rtc, 32.768khz osc
[00:44:04]<Thetawaves> x2
[00:44:26]<djdelorie> it's a standard crystal clock circuit...
[00:44:28]<Thetawaves> never seen a clock with R14
[00:44:42]<Thetawaves> what is the load of X2?
[00:45:44]<djdelorie> depends on the crystal. you can always put a 0R there if that's what your crystal wants
[00:46:36]<djdelorie> if I ever respin that board, both clocks get both a series and parallel resistor footprint, "just in case"
[00:47:09]<djdelorie> next flaky board, I'll try a 0R and see if it helps.
[00:47:15]<Thetawaves> but that will put them unnecessarily far from the chip
[00:47:25]<Thetawaves> causing excessive stray capacitances that will throw the freq off
[00:47:59]<djdelorie> they're not that far from the cpu anyway, and the stray pF should be accounted for in the load caps anyway
[00:48:25]<Thetawaves> i'm trying to find the equation
[00:48:32]<Thetawaves> damn, i've got tons of pdfs open
[00:48:42]<djdelorie> you need more monitors :-)
[00:49:28]<Thetawaves> but it's like ((C1 + C1s) * (C2 + C2s))/((C1 + C1s) + (C2 + C2s))
[00:49:40]<djdelorie> I've seen inconsistent information on how to go from the "load capacitance" in the crystal spec, to the actual capacitance on the pcb
[00:50:08]<djdelorie> AFAIK, the caps are just under twice the spec'd load
[00:50:16]<djdelorie> (in general)
[00:50:17]<Thetawaves> so in that schem, you've got a crystal with about 16pf load?
[00:50:25]<djdelorie> something like that
[00:50:48]<Thetawaves> i've seen a lot of missinformation too
[00:51:26]<Thetawaves> you CAN calculate it, and the capacitor values are not 22pf when the crystal calls for 22pf load
[00:51:38]<Thetawaves> moving on
[00:51:43]<djdelorie> the RX spec says 15pF per cap including strays Their eval board uses two 12pF caps.
[00:52:11]<djdelorie> but that assumes you get a crystal that works with those values, too.
[00:52:23]<Thetawaves> definitely
[00:53:28]<Thetawaves> so you've got the cpu split up into a bunch of functional blocks in that schem
[00:53:33]<djdelorie> yup
[00:53:45]<Thetawaves> ahh cool
[00:54:19]<djdelorie> well, one block for power/download, and the rest are just one block per row of pins on the chip

[17:00:19]<rigid> 6 bridges... forgote the gripper
[17:00:33]<archivist> er we do it properly as there is gearing between counts and steps there statement seems to lack variable gearing

[17:02:45]<cradek> jeez I've been working on this project a long time
[17:02:45]<skunkworks> linuxcnc will drive h-bridges and read encoders directly (if you have enough i/o.)

[20:06:00]<tom3p> the oneshot pulse width has a minimum size equal to the period of the FP thread its run on (plus a few uS overhead).
[20:06:11]<tom3p> and the FP thread is likely dependent on the base thread, so you write 'setp oneshot.0.width .000013' and get 1mS
[20:06:13]<tom3p> because the FP thread was .ini'd at 1000000! surprise surprise gomer!
[20:07:15]<tom3p> the src code 'imports/includes' the 'period' and uses FP to get the width (period * .000000001)
[20:09:16]<andypugh> I am vaguely surprised that it is an fp function. It could easily have been a base-thread function with width definied in thread periods.
[20:09:42]<tom3p> yeah making it FP is a waste, we oughtta have tiks
[20:10:26]<tom3p> we express the period in tiks in the .ini
[20:11:01]<andypugh> "edge" looks like it can do the same thing.
[20:11:27]<andypugh> In fact, they appear to have redundant functionality.
[20:12:20]<andypugh> (Except no fp in "edge" so it can run in the base thread)
[20:14:08]<tom3p> where does the value 'period' come from in thqat code?? it doesnt have the 'option data internal'
[20:15:13]<tom3p> voodoo
[20:15:16]<andypugh> It's part of the magic of "comp". Look in the "convenience macros" section.
[20:17:10]-!- PCW [PCW!~chatzilla@99.88.10.65] has joined #linuxcnc[20:17:26]<andypugh> "FUNCTION" gets macro-substituted to void edge(void *inst, long period) (or soemthing like that) in the generated C code.
[20:18:32]<andypugh> (and pin_name gets macro-substituted to *inst->pin_name too)
[20:18:51]<tom3p> ? you mean the reference to fperiod on page 43 of Hal User Manl?
[20:18:56]<andypugh> Comp is part-genius and part horror :-)
[20:19:16]<andypugh> I don't know, I never read the manuals :-)
[20:19:40]<andypugh> I use the online docs: http://www.linuxcnc.org/docs/html/hal/comp.html#_convenience_macros[20:20:06]<andypugh> (period is under FUNCTION )
[20:20:50]<tom3p> anyway, the docs oughtta warn users of the granularity
[20:21:09]<tom3p> thx tho ( reading the link )

[20:22:18]<skunkworks> ;)
[20:23:17]<tom3p> sometimes i walk down to the library
[20:23:20]<andypugh> I would need to create a new branch to push a change to the "oneshot" docs. (and I am in the middle of something). It's a simple matter of editing the .comp file and adding a "description" section though.
[20:23:24]<tom3p> and get inet
[20:23:42]<andypugh> So, how are you managing to be here now?
[20:23:52]<tom3p> at lib now
